Multiple fault codes

[Stacey_308]

Hi, im new to the forum. Having more than the usual issues with my 308.

My car started running rough so I plugged the OBD reader in and got a P1352 fault code in May. Recently a P1349 code has appeared followed by a P0113 and a P0102 code.

Issues with the car:
Sometimes the dials will drop with a few clicks behind them and the lights will flicker. (First thought was damaged wiring, can't see any faults) doesnt idle well, has high fuel consumption compared to usual and smells awful like its choking.

What's have I tried so far:
I've checked the chassis earth point which was cleaned and moved elsewhere. Cleared the codes but reappeared.

I haven't a 9v battery to test the relay so im unsure how to check that but where on earth do I start? Is it normal for this many sensors to have problems at one time or is this a result of my ignorance when the problem arised? I have some contact cleaner coming tomorrow for the relays and switches to see if that helps.

Any help would be appreciated.

It cannot do any harm to do a BSI reset as well as cleaning all the fuse and relay contacts. Clear the fault codes before you start then do all the cleaning and finally carry out the reset. Then see how things go. You may have a battery problem, either the battery management or the battery itself but going through that procedure should help you clarify which fault codes are genuine.

Hi, thank you, I have seen a post about doing a BSI reset. I'll give that a go tomorrow too.
